· Spymac.com has approximately 1 million registered users, making it easily the largest international online community for Mac owners. The home page has 50 links to news stories about Apple, and in one of them we learned to our astonishment that about half of all Mac users are 55 and older. (We would have guessed that it was overwhelmingly young people.)

· OnlineIdols.com is set up like the TV show “American Idol.” You compete by sending a video of yourself singing, dancing or playing an instrument. There’s a new contest every month. Each winner gets $400, and presumably some attention for his or her talent.
